Harmonic functions with varying coefficients

Journal of Inequalities and Applications, 2016
Complex-valued harmonic functions that are univalent and sense preserving in the open unit disk can be written in the form f = h + g ‾ $f=h+\overline{g}$ , where h and g are analytic.

Exploring Bi-Univalent Classes via q-Derivatives and Bivariate Fibonacci Polynomials

Mathematics
The q-calculus framework has emerged as a powerful tool in geometric function theory, enabling refined analysis of analytic and bi-univalent functions.

Harmonic univalent functions

, 2009
Harmonik fonksiyonlar analitik olması gerekmeyen kompleks değerli fonksiyonlardır. Harmonik yalınkat fonksiyonlar teorisi ise kompleks analizin üzerinde en çok araştırma yapılan dallarından birisidir.

On the coefficients of concave univalent functions [PDF]

, 2004
Let D denote the open unit disc and f : D → ℂ̄ be meromorphic and injective in D. We assume that f is holomorphic at zero and has the expansion f(z) = z + ∞σ anzn Especially, we consider f that map D onto a domain whose complement with respect to ℂ̄ is ...
